Method Details

layout

protected void layout(Node nodes)

Description copied from class: Layout.Algorithm

This method has to be implemented to perform the layout.

Specified by:

layout in class Layout.Algorithm

Parameters:

nodes - the first node of the linked list of all nodes

See Also:

• Node

applyVectorToNode

protected void applyVectorToNode(Node nodeTemp,
 Point2d diff,
 double delta)

moveNodesToUpperLeft

protected void moveNodesToUpperLeft(Hashtable nodesTemp,
 Vector no,
 double diffX,
 double diffY)

Moves the nodes in the layout

Parameters:

no - Vector of a node

diffX - the nodes will be moved for diffx-length horizontally

diffY - the nodes will be moved for diffy-length vertically

nodes - Hashtables of nodes

getMinXNodePositionValue

protected double getMinXNodePositionValue(Hashtable nodesTemp,
 Vector no)

Getting the smallest x-value of the coordinates of the nodes

Parameters:

no - Vector of a node

nodes - Hashtable of nodes

Returns:

the smallest x-position value

getMinYNodePositionValue

protected double getMinYNodePositionValue(Hashtable nodesTemp,
 Vector no)

Getting the smallest y-value of the coordinates of the nodes

Parameters:

no - Vector of a node

nodes - Hashtable of nodes

Returns:

Calculating the maximum height and width of the nodes

Parameters:

nodesTemp - Vector with nodes

Returns:

maxBounds the maximum width and height values

disassociateNodes

public void disassociateNodes()

Dividing the nodes of the graph into the two sets of connectedNodes (nodes that have connections to other nodes and unconnectedNodes (nodes that have not edges to other nodes
